Purpose:
The aim of this study is to compare the detection ability of quality of life (QoL) changes and responsiveness of the KOrean QUality of life in Stomach cancer patients Study group (KOQUSS)-40 and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ).
Materials and Methods:
A multicenter prospective observational study was conducted to evaluate QoL changes after various gastrectomies between January 2021 and April 2022. Participants were instructed to complete the KOQUSS-40 and EORTC QLQ-C30/STO22 preoperatively and at 1, 3, 6, and 12 months postoperatively. QoL changes over time and QoL responsiveness were assessed for each questionnaire.
Results:
Data from 491 patients who underwent curative gastrectomy for gastric cancer at 22 institutions were analyzed. The summary scores of the KOQUSS-40 and EORTC QLQ-STO22 showed significant differences between the total and proximal gastrectomy groups (p=0.044 and p=0.038, respectively), but no difference was observed for the EORTC QLQ-C30. Dysphagia on the KOQUSS-40 was significantly different between the total and proximal gastrectomy groups (p=0.031); however, dysphagia on the EORTC QLQ-STO22 did not differ. The responsiveness of the KOQUSS-40 was similar to that of the EORTC QLQ in patients who experienced ≥ 10% body weight loss, but approximately 10% less in patients receiving adjuvant chemotherapy than the EORTC QLQ.
Conclusion
KOQUSS-40 has several advantages over EORTC QLQ-C30/STO22 when comparing QoL between the total and proximal gastrectomy groups. The findings provide information for researchers investigating the QoL of patients who have undergone curative gastrectomy for gastric cancer.

Purpose:
This study evaluated the postoperative quality of life (QoL) after various types of gastrectomy for gastric cancer.
Materials and Methods:
A multicenter prospective observational study was conducted in Korea using the Korean Quality of Life in Stomach Cancer Patients Study (KOQUSS)-40, a new QoL assessment tool focusing on postgastrectomy syndrome. Overall, 496 patients with gastric cancer were enrolled, and QoL was assessed at 5 time points: preoperatively and at 1, 3, 6, and 12 months after surgery.
Results:
Distal gastrectomy (DG) and pylorus-preserving gastrectomy (PPG) showed significantly better outcomes than total gastrectomy (TG) and proximal gastrectomy (PG) with regard to total score, indigestion, and dysphagia. DG, PPG, and TG also showed significantly better outcomes than PG in terms of dumping syndrome and worry about cancer. Postoperative QoL did not differ significantly according to anastomosis type in DG, except for Billroth I anastomosis, which achieved better bowel habit change scores than the others. No domains differed significantly when comparing double tract reconstruction and esophagogastrostomy after PG. The total QoL score correlated significantly with postoperative body weight loss (more than 10%) and extent of resection (P<0.05 for both).Reflux as assessed by KOQUSS-40 did not correlate significantly with reflux observed on gastroscopy 1 year postoperatively (P=0.064).
Conclusions
Our prospective observation using KOQUSS-40 revealed that DG and PPG lead to better QoL than TG and PG. Further study is needed to compare postoperative QoL according to anastomosis type in DG and PG.

Proactive planning and preparation are critical to the safety of patients on dialysis during emergencies, such as natural disasters, and pandemics, such as coronavirus disease 2019. Patients with end-stage kidney disease are particularly vulnerable to disruptions such as power outages, water shortages, transportation issues, and dialysis center closures because they can result in missed dialysis sessions and severe health deterioration. This study aimed to develop tailored dietary guidelines for Korean patients on hemodialysis by applying the U.S. Centers for Disease Control and Prevention guidelines and considering the dietary limitations of these patients. The proposed guidelines impose strict potassium, phosphorus, sodium, and fluid restrictions and include two 3-day emergency meal plans: one for scenarios involving disruptions of electricity and water supply and another for situations in which these utilities are available. The use of a food exchange list enhances the dietary flexibility of these patients. Although these guidelines cannot replace dialysis, they could mitigate the impact of emergencies on patient health by providing essential support during critical periods.

Background:
Cholecystitis is an important risk factor for gallbladder cancer, but the bile microbiome and its association with gallbladder disease has not been investigated fully.We aimed to analyze the bile microbiome in normal conditions, chronic cholecystitis, and gallbladder cancer, and to identify candidate bacteria that play an important role in gallbladder carcinogenesis.
Methods:
We performed metagenome sequencing on bile samples of 10 healthy individuals, 10 patients with chronic cholecystitis, and 5 patients with gallbladder cancer, and compared the clinical, radiological, and pathological characteristics of the participants.
Results:
No significant bacterial signal was identified in the normal bile. The predominant dysbiotic bacteria in both chronic cholecystitis and gallbladder cancer were those belonging to the Enterobacteriaceae family. Klebsiella increased significantly in the order of normal, chronic cholecystitis, and gallbladder cancer. Patients with chronic cholecystitis and dysbiotic microbiome patterns had larger gallstones and showed marked epithelial atypia, which are considered as precancerous conditions.
Conclusion
We investigated the bile microbiome in normal, chronic cholecystitis, and gallbladder cancer. We suggest possible roles of Enterobacteriaceae, including Klebsiella, in gallbladder carcinogenesis. Our findings reveal a possible link between a dysbiotic bile microbiome and the development of chronic calculous cholecystitis and gallbladder cancer.

Voriconazole, a triazole antifungal agent used to treat serious fungal infections, has a pharmacokinetic characteristic of undergoing hepatic metabolism by the cytochrome P450 system. Few cases of hyperkalemia have been reported, which presented only when the serum voriconazole level was exceptionally elevated by drugdrug interactions. Additionally, azole antifungals may interfere with the biosynthesis of adrenal steroids and therefore can predispose patients to aldosterone deficiency. However, it is unclear whether voriconazole itself can induce hypoaldosteronism or hyperkalemia. Here, we report a case of voriconazole-induced hyperkalemia in a patient administered concurrent medications to treat comorbidities. Voriconazole was orally administered for pulmonary aspergillosis, and three episodes of severe hyperkalemia recurred, which improved with emergency treatment. In the first episode, renin-angiotensin-aldosterone system inhibitors were associated. We found that dronedarone might have increased the voriconazole level in the second episode. At that time, severe hypercalcemia was concurrent, which improved with acute hemodialysis and eliminating dronedarone. Finally, severe hyperkalemia recurred without concurrent medications known to interact with voriconazole. Upon switching from voriconazole to itraconazole, the hyperkalemia was resolved. Drug level monitoring is necessary when voriconazole is used. Genetic susceptibility, such as through CYP2C19 polymorphism, may be investigated for patients with adverse reactions to voriconazole.

BACKGROUND: Previous studies have revealed an association between health behavior and household type; moreover, there have been debates on the relation between drinking behavior and household type. Therefore, we examined drinking behavior of one-person households and compared the differences with multi-person households.METHODS: This study analyzed 8,966 participants, aged 19 years or older, in the 6th Korea National Health and Nutrition Examination Survey (2013, 2015). All participants were categorized into one- and multi-person households. The general characteristics were extracted using a chi-square test, and the risk of drinking behavior of one-person households was analyzed via multiple logistic regression.RESULTS: There were no statistically significant differences in the drinking behavior of men by household type. However, the risks of binge and problem drinking were 3.242 times (95% confidence interval [CI], 1.624–6.471) and 2.488 times (95% CI, 1.097–5.642) higher, respectively, in one-person household women than in multi-person household members aged between 19 and 39 years. Furthermore, the risk of problem drinking was 2.266 times (95% CI, 1.126–4.561) higher in one-person household women than in multi-person household members aged between 40 and 64 years.CONCLUSION: Considering the increasing trend of one-person households, follow-up studies on drinking behavior of one-person households are needed; the findings of these studies need to be used to prevent alcohol-related diseases and socio-economic problems.
